Phoenix Framework & LiveView Thinking

About

This skill transforms Claude into a specialized Phoenix Framework architect, focusing on high-performance Elixir patterns and the reactive LiveView lifecycle. It enforces the 'Iron Law' of avoiding duplicate database queries in mount/3, guides the implementation of security-first scoping for multi-tenant applications, and provides battle-tested patterns for PubSub, async data loading, and GenServer integration. By identifying common pitfalls like stale socket states or insecure file uploads, it ensures your Phoenix applications are scalable, secure, and idiomatic.

Key Features

• Provides async data loading patterns using modern LiveView primitives like assign_async.
• Identifies architectural red flags including stale socket states and incorrect cleanup methods.
• Enforces optimized LiveView lifecycle management to prevent duplicate database queries.
• Guides efficient PubSub topic scoping and real-time communication architecture.
• 0 GitHub stars
• Implements security-first scoping patterns for multi-tenant data access (Phoenix 1.8+).

Use Cases

• Refactoring Elixir applications to modern Phoenix 1.8 security and scoping standards.
• Building reactive, real-time dashboards with optimized LiveView data fetching.
• Debugging complex lifecycle issues, performance bottlenecks, and PubSub data leaks.
